Question

Your customer needs an automated system to patrol the highways. The job of the system is to collect the following information on vehicles traveling down a certain stretch of highway: license plate number, current speed, and speed limit. A program is required to determine if a speeding ticket is needed for each set of data. Ticket will only be issued when number of miles per hours (mph) over the speed limit is at least 5 mph. Ticket prices are calculated as follow: base + fee * <number of mph over the speed limit>. The base is always $150 and the fee per mph over the speed limit is varied according to number of mph over the speed limit. The fee per mph over the speed limit is $5 when number of mph over the speed limit is no more than 20 mph. However, the fee per mph over the speed limit is $10 when number of mph over the speed limit is between 20 mph and 50 mph. In addition, a ticket of $1000 is automatically given to vehicle when number of mph over the speed limit is more than 50 mph. You can assume that valid data will be provided, and your program must allow the processing to be repeated until a sentinel value of “QUIT” is entered. It must display percent of ticketed vehicles and average ticket amount. Follow the user-interface as shown below including 2 digits after the decimal point. You must run the following test cases as one run. [Provide some useful information about AHP program including your name, version, and instructions, etc.) Enter a license plate number -=> ABC123<Enter> Enter current vehicle's speed --> 60<Enter> Enter speed limit in the zone --> 55<Enter> Vehicle travelled 5 miles over the speed limit. A ticket of $175 is issued to ABC123. Enter a license plate number --> 123XYZCEnter> Enter current vehicle's speed -=> 59<Enter> Enter speed limit in the zone --> 55<Enter> Vehicle travelled 4 miles under the speed limit. No ticket is issued to 123XYZ. Enter a license plate number --> FASTONE<Enter> Enter current vehicle's speed --> 80<Enter> Enter speed limit in the zone --> 50<Enter> Vehicle travelled 30 miles over the speed limit. A ticket of $450 is issued to FASTONE. Enter a license plate number --> QUIT Enter> Tickets were given to 2 out of 3 vehicles. Percent of ticketed vehicles: 66.67% Average ticket amount: 312.50 Thank you for using our AHP program. Additional Requirements: You must utilize modules/functions in your program. There must be at least 4 modules/functions: program information, input data, calculation, and display results. DO NOT use global variables in your program. Start with the design by identifying the modules/functions, drawing the hierarchy chart, and coming up with the pseudocode for each

just the extra credit part please

int main()
{
        char lno[50];
        char e[5]="QUIT"; 
        int csp,sl;
    clrscr();
        while(1)
        {

            // lno is a character array variable. csp and sl are integer variable
            cout<<"Enter license plate number: ";
            cin>>lno;
            if(strcmp(lno,e)==0) break;  //break the while loop if license number gets QUIT
            cout<<"Enter current vehicle speed: ";
            cin>>csp;
            cout<<"Enter speed limit: ";
            cin>>sl;
            int diff=csp-sl;                      // calculating the difference between mph and speed limit
            cout<<"vehicle travelled "<<diff<<" miles over the speed limit"<<endl;
            calculation(lno, diff);
            total++;                //counting total vehicles
        }
        display();
    getch();
        return 0;
}

Please have a look on the C++ code above, although i have explained complete logic using java and pseudo code.

This is a good question, lets analyze the conditions in the given question:

The ticket will only be issued if the speed (miles/hrs) exceeds the speed limit by atleast 5 mph.

We also know that ticket prices are calculated on the following formula.

Ticket Price = Base+Fee*<number of mph over the speed limit>

Base is always $150, and Fee depends on the number of mph over the speed limit

No fee charges if mph over the speed limit is less than 5mph.

Fee charges per mph is $5 if mph over the speed limit not more than 20mph

Fee charges per mph is $10 if mph over the speed limit lies between 20mph and 50mph

However an additional $1000 charged, if number of mph exceeds speed limit more than 50mph.

Now lets analyze the pseudocode and understand it with java program.

import java.util.Scanner;    //importing Scanner class for taking input
class Ticket                  //name of class is ticket
{
    int total=0, charged=0, fare=0;            //variable used for counting total,charged vehicles and total amount                                                                              //charged
    public static void calculation(String s, int diff)               //function which performs calculation part
    {
        if(diff>50)                                         // if mph exceeds speed limit by 50
        {
            System.out.println("a ticket of $1000 is issued to "+s);
            charged++;                                  // counting the number of charged vehicles
            fare=fare+1000;                           // charged $1000 and we add it to total amount charged
        }else if(diff>20)
        {
            int ticket=150+10*diff;                // applying formula, base=$150, fee=$10
            System.out.println("a ticket of $"+ticket+" is issued to "+s);
            charged++;                                //counting the number of charged vehicles
            fare=fare+ticket;                        // storing the ticket charge to total amount charged
        }else if(diff>=5)
        { 
            int ticket=150+5*diff;                //applying formula, base=$150, fee=$5
            System.out.println("a ticket of $"+ticket+" is issued to "+s);
            charged++;                              // counting number of charged vehicles
            fare=fare+ticket;                      // add ticket charge to total amout charged
        }else
        {
            System.out.println("no ticket is issued to "+s);  // if no amount charged
        }
    }
    public static void main(String args[])
    {
        Scanner sc=new Scanner(System.in);
        String lno; int csp,sl;
        //taking input
        while(true)
        {

            // lno is a string variable. csp and sl are integer variable
            System.out.println("Enter license plate number: ");
            lno=sc.nextLine();
            if(lno=="QUIT") break;  //break the while loop if license number gets QUIT
            System.out.println("Enter current vehicle speed: ");
            csp=sc.nextInt();
            System.out.println("Enter speed limit: ");
            sl=sc.nextInt();
            int diff=csp-sl;                      // calculating the difference between mph and speed limit
            System.out.println("vehicle travelled "+diff+" miles over the speed limit");
            calculation(lno, diff);
            total++;                //counting total vehicles
        }
        display();
    }
